The invention relates to the field of ultra-wideband pulse communication, and provides a multi-base station broadcast communication method and device based on ultra-wideband pulse. A base code elementis formed by using a ternary complete sequence and a cyclic prefix at an emit end, the base code element is modulated by using a binary ASK modulation manner, and each broadcast base station uses themechanism to send a broadcast signal; at a receive end, a reasonable received signal sampling window is set, a terminal receiver performs self-correlation on signals of a period taken out from the sampling window, the self-correlated signals are determined according to a noise detection threshold set by the receiver, so as to complete decoding. In the method, energy of each path of signal is utilized fully, so as to convert disadvantages of multi-path transmission into advantages and preventing impact of rapid attenuation of a channel. Each base station broadcasts a signal at an identical frequency simultaneously, and a terminal in an overlapped area of base stations does not has a problem of signal conflict of base stations, but the signal to noise ratio is improved.
